1. CYPEINID^ — NOTEMIGONUS.

griucliug surface, the edges of which are more or less creiiate. Alimen- 
tary canal short, though rather longer than the body. Size rather 
large. As here understood, Notemigonus differs from the European 
Ahramis (Bream) only in the much shorter anal fin — from 9 to 20 rays in- 
stead of 30 to 40. All its species are American. There is much varia- 
tion in the length of the anal and in the form of the mouth among the 
species left in Ahramis, and a reunion or a different division of the 
group may be necessary, {^comc, back; rjtv., half; yihoz, angle; the 
back being almost carinated.)
